Detailed Specifications
HPE 1990-4363 1Gb 1000Base-LH SFP Transceiver
Overview
The HPE 1990-4363 is a 1 Gb small-form-factor pluggable (SFP) transceiver designed for long-distance single-mode fiber links. It uses a 1550 nm laser to achieve up to 70 km reach over SMF (single-mode fiber). It is suited for enterprise campus backhaul, data-center interconnects or branch-office WAN links. The transceiver fits any compatible SFP slot on HPE / Aruba switches, routers or other networking equipment, and supports standard Gigabit Ethernet signaling.
